Alien hunters claim this image shows a dead woman wearing a dress sprawled out on Mars.

UFO fans have described the bizarre spot as “the find of the century” after it was shared on a conspiracy blog.

Alien obsessive Scott C. Waring shared the picture on UFO Sightings Daily - and included a colourised a version to highlight the female shape.

Scott wrote: “This is one of the few carvings I have found on Mars that depict a human-like species.

“I have found hundreds, but never looking human, and her dress is raised up in the front, and longer in the back, much like the ladies used to wear back in the 1700s here on Earth.”

The strange sight was spotted a few weeks after conspiracy theorists claimed to have spotted an ' alien missile ' on the moon.

They believed a picture - thought to have been taken on July 20, 1969 during the Apollo 11 mission to the moon - showed the mystery aircraft flying over the celestial body.

It was featured in a YouTube video on the Paranornal Crucible channel - a common destination for bizarre conspiracy theories and supposed UFO sightings.

The video was posted earlier this month and has already notched up over 100,000 views.

"Bizarre image from the Apollo archives which appears to show a missile type UFO cruising across the moon," reads the explanation under the video.

"Could NASA be bombing alien installations on the lunar surface, possibly using high tech ships from the secret space program. Very odd object, not convinced its an alien craft, more likely something we launched, but at who and why."
